Feighery, Dalton, Ga., assignors to Tex Del Corporation, Dalton, Ga., a corporation of Georgia Filed Mar. 17, 1964, Ser. No. 352,451 6 Claims. (Cl. 112-64) This invention relates to a fringe-forming machine, and has particular reference to a machine for forming fringes to be sewed to rugs, but not necessarily limited to such use.

A number of machines have been developed which form fringes of the type referred to, but such machines are relatively complicated in principle, and it is an important object of the present invention to greatly simplify the operation of forming, sewing and cutting the loops in the yarn to form the finished fringe.

A further object is to provide novel traveling means for supporting successive turns of yarn wound therearound, to stitch longitudinally between the traveling means, and then, as the stitched material moves, to cut the loops adjacent the traveling means to form the fringe ends.

More specifically, an object of the invention is to provide parallel flexible elements having remote runs moving in the same direction, and to provide novel revolving means for wrapping successive turns of yarn across and around the flexible elements to form successive loops.

A further object is to provide a novel arrangement of parts wherein the loops are continuously stitched intermediate the runs of the flexible elements as the yarn is carried therealong; to cut the loops extending around the remote runs of the flexible elements after the stitching operation is performed, and then to collect the thus finished fringe from the machine for subsequent use.

Other objects and advantages of the invention will become apparent during the course of the following description.

In the drawings I have shown one embodiment of the invention. In this showing FIGURE 1 is an elevation of the machine looking from one side thereof, portions of the supporting framework being broken away at the bottom thereof;

FIGURE 15 is an end view of the finished fringe showing the mode of attaching it to a rug.

The general principles of the apparatus may be first set forth to aid in an understanding of the apparatus as a whole. Referring to FIGURES 1, 4 and 10, yarn is fed through a goose-neck tube 20 rotating on an axis indicated as 21 so that the tube swings through a continuously circular path. The yarn fed from the tube is wound about spaced chains 22 (FIGURE 4), the outer runs of which move away from the goose-neck tube 20 to make room for successive turns of the yarn about the chains. The yarn is thus wound substantially as shown in FIGURE 12, the yarn 24 being looped at its ends as at 25 around the chains. As the looped yarn moves away from the goose-neck tube 20, it is stitched as at 26, parallel to the chains, whereupon the loops 25 are cut as at 27 (FIGURE 13), thus freeing the yarn from the chains with fringes formed on opposite sides of the stitching 26. The product thus completed is with drawn from the chains to make room forthe additional supply of yarn loops, and the finished product is Wound upon a suitable roll.

Referring to FIGURES 1, 10 and 11, the numeral 30 designates a stand carrying at the upper end thereof bearings 31 in which is mounted for rota-tion on the axis 21 a tubular shaft 32 into one end of which is supplied yarn strands 33, twisted, as will become apparent below, to form fringe threads.

The left-hand end of the tubular shaft 32 carries an apertured bracket arm 35 through which the thread is fed as at 36 to enter the portion 37 of the tube 20 which diverges from the axis 21. The remote end 38 of the goose-neck tube 20 is turned inwardly to feed therefrom the thread to be wrapped around the chains 22 as the tubular shaft 32 and goose-neck tube are rotated. This rotation may be effected in any suitable manner, for example, by a motor 40 (FIGURE 1) which may have a conventional speed reducing gearing driven thereby and connected to a drive chain 41 passing around a sprocket 42 on the tubular shaft 32.

Spaced to the right of the stand 30 in FIGURE 10 is shown a support 45 welded or otherwise secured to a base 46 by which the lower end of the stand 30 is also carried. Welded or otherwise secured to the upper end of the support 45 is a frame 47 of substantial V-shape carrying a central mandrel 48 (FIGURE 11) and remote angular mandrels 49 fixed to brackets 50 carried by the frame 47. These mandrels carry yarn spools as at 51 and the yarn is pulled simultaneously to a junction point 52 where the yarns enter the tubularrnernber 32, and the rotation of the member 32 and arm 20 twist the strands of yarn spirally to form the threads? The fringe-forming portion of the apparatus is shown in FIGURES 1, 2, 4 and 7. Details of the chain arrangement are shown in FIGURES 5 and 6. The fringelforming portion of the apparatus comprises a supporting frame indicated as a whole by the numeral 55, supported on the base 46. Since this frame is a matter of design and forms no part of the present invention, the component parts thereof need not be specifically referred to. The chains 22 pass around rear sprockets 56 and forward sprockets 57. The sprockets 56 are carried by vertical shafts 58 extending downwardly through plates 60 (FIGURES 2 and 4) adjustably mounted by bolts 61 movable in slots 62 and threaded in parallel members 63. These members (FIGURE 7) are machined steel plates forming guides for the supporting plates 60 and are secured to parallel members 64 of the frame structure. Each plate 60 is provided with a depending portion 66 (FIGURES 2 and 7) carrying a horizontal extension 67 rotatably supporting a rotating shaft 68 at its lower end. Each of these shafts is provided with a bevel gear 70 meshing wit-h a similar gear 71 mounted on a transverse shaft 72. Such shaft is suitably journaled in hearings in the main frame and also in vertical bearing extensions 74 carried by the depending plate portions 66. The shaft 72 is driven by chain 76 connected to be driven by a gear reducer 77 supported in the frame and power driven in a manner to be described.

Referring to FIGURES 4, 5 and 6, an elongated supporting plate 80 is attached to each plate and projects forwardly therefrom to support the associated chain 22. The inner edges of the plates are extended upwardly to form flanges 81 (FIGURE 12) over which the yarn is wound in forming the loops. A divider or spacer 82 is arranged between the runs of each chain to prevent the outer runs of the chains from swinging inwardly under a certain degree of pull exerted thereon by the loops of yarn.

The bolts 61 may be loosened to move the plates 60 toward each other to vary the spacing between the chains 21 and thus vary the width of the fringe to be formed. The forward ends of the chains, of course, must be subject to similar adjustment. To this end, each sprocket 57 is mounted on a vertical shaft 84 projecting through the plate 80. Each shaft 84 (FIGURES 4 and 6) also projects through a top wall 85 formed integnal with the flange 81, the forward ends of the chains thus being housed. The sprockets 57 are rotatable on the shafts 84 and each of the latter is provided below the plate 80 with an apertured head 87 through which slidably passes a threaded spacer rod 88. Nuts 89 on this rod engage opposite sides of each of the heads 87 to fix them against movement longitudinally of the rod 88.

Referring to FIGURE 2, it will be noted that the chain 76 passes around sprockets 92 and 93, respectively mounted on the shaft 72 and on the output shaft 94 of the speed reducer 77. The input shaft 95 of the speed reducer 77 is provided with a pulley 96 and a belt 97 passes around this pulley and around a pulley 98 (FIGURE 9) on a long tranverse shaft 100 which extends throughout the width of the main frame structure 55 and across an auxiliary frame structure 101 (FIGURE 2). The shaft 100' is a drive shaft for the speed reducer and thus transmits power to the shaft 72 to drive the chains 22.

In the auxiliary frame 101 is mounted an electric motor 104, the drive shaft of which carries a pulley 105, and a belt 106 passes around this pulley and around a pulley 107 on the shaft 100. The latter shaft also carries a pulley 108 (FIGURE 3) and a belt 109 passes around this pulley and around a pulley 110 on a shaft 111, supported in suitable bearings in the auxiliary frame 101. On the inner end of the shaft 111 (FIGURE 2) is mounted a pulley 114, and a belt 115 passes around this pulley and around a pulley 116 mounted on a transverse shaft 117 supported in suitable hearings in the main frame structure. Two pulleys 118 (FIGURES 2, 4 and 7) are carried by the shaft 117. Round belts 119 pass around these pulleys and around pulleys 120 mounted on vertical shafts 121, the belts 119 turning as shown in FIGURES 4 and 7 to transmit rotation from the horizontal shaft 117 to the vertical shafts 121. The latter shafts are supported in bearings 122 carried by bracket arms 123 fixed as at 124 to the respective plates 60. The lower end of each shaft 121 carries a rotary cutting blade 127, each blade being arranged in close proximity to the outer run of one of the chains 22 to cut the loops wrapped around the chains as referred to above. Each blade 127 is provided with a sharpening device (not shown) which is conventional and forms no part of the present invention.

Referring to FIGURES 1 and 2, and particularly to FIGURE 1, the shaft 72 is provided with a sprocket 139 about which passes a chain 131. This chain passes around idler sprockets 132 and 133, thence upwardly at an angle around a sprocket 134 mounted on a shaft 135. This shaft is mounted in bearings as shown in FIGURE 2, carried by the main frame, and intermediate its length carries a relatively long roller 139, which is a feed roller for taking off completed fringe from the apparatus, as described below.

In contact with the roller 139 is a press roll 141 mounted on a shaft 142, opposite ends of which are rotatable in arms 143 pivoted at their ends as at 144 (FIG- URE 8) on upstanding brackets 145 suitably carried by the main frame 55.

The shaft 135 of the feed roll carries a pulley about which passes a belt 151. This belt passes around a pulley 152 on a shaft 153 journaled at its ends in bearings 154 carried by the upper ends of supporting arms 155 (FIG- URES 1, 2 and 3). Intermediate its ends, the shaft 153 carries a gathering roll 156 (FIGURE 2) on which the finished fringe is wound as it is fed between and from the rolls 139 and 141. Extending across the main frame adjacent the top thereof is mounted a shaft 1611 supported in bearings carried by the main frame and beyond one side of the latter (FIGURE 2) a sprocket 161 is mounted on the shaft 160. A chain 162 passes around the sprocket 161 and around a sprocket 163 carried by the shaft 106.

As shown in FIGURES 2 and 3, the shaft carries a pulley 165, about which passes a belt 166. A suitable sewing machine, indicated as a whole by the numeral 168, is suitably supported by the frame structure and carries a driven pulley 169 about which the belt 166 passes. The sewing machine is preferably of the two-needle, fourthread type of standard construction and need not be described in detail. It will be understood that this machine stitches the moving loops between the chains 22 as indicated by the lines 1711 in FIGURE 4. The sewing machine, of course, has the usual bed 171 (FIGURE 1) arranged just below the horizontal plane of the chains 22. Thus successive turns of the fringing material about the chains will be stitched prior to the cutting of the loops around the chains by the rotary blades 127. The finished fringe may be stitched as at 172 along the edge of a rug 173.

Operation The chain 22 constitutes the forming elements of the apparatus. They are essentially endless elements with remote runs traveling in the same direction to carry away from the winding point the successive turns of yarn about the chains. The chains are driven by the respective shafts 58 which, in turn, are driven through the bevel gears 70 and 71. The shaft 72 (FIGURE 2) on which the gears 71 are mounted is driven by the speed reducer 77 through the chain 76.

The yarn is wrapped around the chains in the manner suggested in FIGURE 12 and the thickness and formation of the yarn thread depends upon the feed means from the source. For example, the creel or support 47 (FIG- URE 11) may carry three cones or mandrels 49, or more or less than this number depending upon the thickness of the yarn and the number of strands to be wound. The thicker the twisted yarn, the slower the tubular member 32 (FIGURE 10) will operate in proportion to the linear speed of the outer runs of the chains, to control the feeding of the arm so that successive turns will properly lie adjacent and in contact with each other.

Rotation of the feed member or goose neck 20 obviously wraps successive turns of yarn around the chains, and the speed of the parts is so coordinated that upon each complete rotation of the goose neck 20, the outer runs of the chains will move a distance equal to one thickness of the yarn wound on the chains. These successive turns of yarn are moved away from the feed point continuously and toward the discharge ends of the chains, that is, the upper or back ends as viewed in FIGURE 4. The

goose-neck 20 provides for the relatively free movement of the yarn therethrough. It will be apparent that if movement of the yarn is substantially resisted, it Will be stretched across the tops and bottoms of the flexible elements 22, with the result that when the yarn is cut, as referred to below, it contracts so that the individual threads of yarn are shorter than the distance between the remote runs of the flexible elements. With the arrangement described, the yarn fits snugly around the flexible elements but is not appreciably stretched so that the flexible elements can be adjusted with respect to each other to provide any predetermined fringe length.

Between the winding point and the rotary blades 127, the sewing machine 168 will be driven to stitch opposite sides of the turns of yarn together as at 26 (FIGURE 13). The sewing machine is driven (FIGURE 3) by the belt 166 passing around the pulleys 165 and 169. The shaft 160, carrying the pulley 165, is driven by the chain 162 (FIGURE 2) from the shaft 100, this shaft being driven by the motor 104 as shown in FIGURE 2.

After successive turns of yarn have been stitched together, the loops 25 (FIGURE 12) are ready to be severed. These loop ends 25, after the stitching operation, pass the rotary blades 127 which cuts the loops as at '27 (FIGURE 13).

At this point, attention is invited to the fact that the plates 80 (FIGURES 5 and 6) arranged beneath the chains are fixed at their back ends to the plates 60 and have their forward ends, as Well as the chains, projecting freely for the winding operation, as shown in FIGURE 7. The chains operate on the plates 80 and the runs of the chains are spaced by the plates 82 (FIGURE 5), thus preventing any inward pull of the yarn loops on the outer runs of the chains from causing such chain runs to be pressed inwardly toward each other. The upwardly projecting flanges 81 (FIGURES 4 and 5) engage the upper portions of the turns of the yarn to form a smooth sliding edge therefor and to prevent the yarn from catching in the links of the chains.

The rotary blades 127 are driven by the belts 119 passing around the pulleys 118 on the shaft 117, and this shaft, in turn (FIGURE 2) is driven by the belt 115 from the shaft 111, the latter shaft (FIGURE 3) being driven from the shaft 100, rotated, as previously stated, by the motor 104.

The operations above described may be started manually in any suitable manner, for example, by manually winding the first turn of yarn and passing the leading free end of the yarn beneath the top of the first turn to anchor this first turn with respect to the chains. After the winding, stitching and cutting operations are completed, the fringe will be cut loose from the chains and the advancing end of the completed fringe will be fed manually between the rolls 139 and 141 (FIGURES 2 and 8) and then led to the winding roll 156 to be wound and gathered thereon to any length. This winding roll is made detachable in any suitable manner, and after a suitable amount of the fringe has been gathered thereon, it is removed and replaced by another winding roll, the fringe being cut and the then advancing edge being wound around the winding roll 156.

The roll 141 (FIGURE 8) is a press roll supported by the pivoted arms 143 to maintain the fringe in engagement with the roll 139, which is positively driven by the chain 131 (FIGURE 1) from the shaft 72, driven as stated above, from the speed reducer 77. The winding roll 156 is driven from and at the same speed as the feed roll shaft 135 by the belt 151. The linear speed of the roller 139 will be the same as the linear speed of the remote runs of the chains 22.

From the foregoing it will be apparent that the present invention is simple in its principle of operation, the rotating goose-neck arm 20 feeding yarn to the chains or other flexible elements 22 with the speed of movement thereof coordinated with the speed of rotation of the goose neck 20 so that the outer runs of the chains move during each rotation of the goose neck arm 20 a distance equal to the thickness of one strand being wound on the chain. Actually, the speed of rotation of the goose neck arm 20 does not control the speed of movement of the yarn from the goose neck tube, the yarn being pulled from the tube by the chains as the yarn is wound thereon. The speed of rotation of the tube 20 is important for the reason given, and the rotation of the hollow tube 32 is important for two reasons: (1), it determines the speed of rotation of the tube 20, and (2) it effects the twisting of the yarn into spiral form, as desired, before the yarn is fed to the chains. The speed of operation of all of the elements of the apparatus may be constant and directly coordinated with each other, except for the rotation of the goose-neck arm 20. The speed of rotation of this tube is controlled, as stated, in accordance with the thickness of the yarn being wound on the chains. The machine is continuous in operation and performs the three main steps of winding the yarn on the chains 22, stitching together the upper and lower strands of the yarn, and the cutting of the loops of the yarn by the rotary blades 127. The power-driven take-off means is important since it disposes of and collects the finished fringe and prevents it from gathering in the machine upon completion of the three operations referred to.

The fringe made with the present apparatus is particularly intended for use with rugs. As shown in FIG- URE 14, the fringe is stitched at 26 immediate the edges of the fringe. When the fringe is to be attached to a rug, it is laid fiat, as shown in FIGURE 14, across the edge of a rug, and then stitched as at 172 to the rug 173 (FIG- URE 15 If the stitching 26 is done centrally of the width of the fringe, then when the portion overlying the rug is swung outwardly to the position shown in FIGURE 15, the upper fringe elements will be slightly shorter than the lower ones. If it is desired that all of the fringe elements be of the same length, the line of stitching 26 may be sufliciently offset from the center of the fringe the proper distance to compensate for the swinging over of the fringe to the position shown in FIG- URE 15.

It is to be understood that the form of the invention shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of the parts may be made as do not depart from the spirit of the invention or the scope of the appended claims.
